AP0100CS HDR: Image Signal Processor (ISP)

Image Flow Processor

Image and color processing in the AP0100CS is implemented as an image flow processor

(IFP) coded in hardware logic. During normal operation, the embedded microcontroller

will automatically adjust the operating parameters. For normal operation of the

AP0100CS, streams of raw image data from the attached image sensor are fed into the

color pipeline. The user also has the option to select a number of test patterns to be

input instead of sensor data. The IFP is broken down into different sections, as outlined

in Figure 12.
